Only thing is: if you feed with rabbit food, you'll have to add in some extra proteine, either like cat dry food sometimes, or as supplying with various insect a few times a week (the ones you can get at the pet store).hyshqa said:Rat, gerbil, hamster and rabbit foods are all fine for mice, though I'd avoid pellet based food or those that list 'grass pellets' as a high portion of the feed as in general the mice won't eat them.
It might be worth you considering adding other grains to the mix, for example oats or barley etc. In the wild mice have a very bland diet compared to the colourful mix of stuff they get in commercial food mixes so creating a 50/50 mix of rodent food and oats for example would be great for the mice and probably work out more cost effective for you![]()
